摘　　要：喷灌技术在我国农业灌溉领域应用较广。目前常规使用的固定式喷头、旋转式喷头和孔管式喷头由于不能实现高低压的自动转换,无法同时兼顾远近射程的不同需求。而脉冲式喷头虽可对灌溉区域进行间断均匀地调节,但费用偏高,广大农民消费不起。笔者从节能的视角出发,设计出一种能实现高低压自动转换的喷头装置,且价格低廉、操作简便,在我国农村地区具有较大的推广空间。Sprinkler technique is widely used in farmland irrigation in China. Commonly-used sprinkler such as fixed sprinkler, rotational sprinkler and multi-hole pipe sprinkler can not transform between low pressure and high pressure automatically. Consequently, they can＇ t simultaneously meet the needs of far range and near range. Pulsed sprinkler can irrigate the cropland interruptedly and evenly, however, the price of it is so high that most farmers can＇t afford to buy it. From the perspective of saving energy,a new sprinkler device was designed that could transform between low pressure and high pressure automatically. Because of its low cost and flexible operation, this design would be widely used in rural areas in China.
